PVE 3 - Unable to backup a specific Windows 2012 VM

[TechSean]

I'm in the process of migrating from PVE 3 to PVE 5. First I backed up and restored all the Containers and that went smooth. Next I backed up 2 non-critical Win2012 VMs, and those were fine.

Now, when I try to back up this last Win2012 VM, it just hangs on the backup.

INFO: starting new backup job: vzdump 112 --remove 0 --mode stop --compress lzo --storage local --node pve4
INFO: Starting Backup of VM 112 (qemu)
INFO: status = stopped
INFO: update VM 112: -lock backup
INFO: backup mode: stop
INFO: ionice priority: 7
INFO: creating archive '/var/lib/vz/dump/vzdump-qemu-112-2017_07_26-16_33_30.vma.lzo'
INFO: starting kvm to execute backup task

INFO: status: 0% (3735552/37580963840), sparse 0% (3514368), duration 3, 1/0 MB/s

Stayed at 0% for 45 minutes before I killed the backup job. (then other VM backups completed in less than 10 minutes and were of similar disk space)

I'm pretty new to Proxmox, so please bare with me if I haven't provided some basic information.

Suggestions?

Post also a pvereport about your system.

This is no longer an issue. Was able to do a snapshot backup instead of a stopped one. Go figure. Everything is now on PVE5
